Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 15 September 2027 at 23:04.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon is entering ♊ Gemini

Moon is passing first ∠4° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1910"

Lunar disc appears visually 0.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1910" and ∠1911".

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2027 after 24 days on 15 October 2027 at 13:47.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 342 / 1295

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 342 of Meeus index or 1295 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.37 days

The length of the lunation is 29 days, 8 hours and 55 minutes. It is 2 hours and 5 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 3 hours and 49 minutes shorter than the mean synodic month length. It is 2 hours and 20 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠18.2°

At the beginning of the lunation cycle the true anomaly is ∠18.2°. At the beginning of next synodic month the true anomaly is going to be ∠36.7°.

Moon before apogee

9 days after point of apogee on 11 September 2027 at 23:39 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 27 September 2027 at 20:12 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 375 363 km

The Moon is 375 363 km (233 240 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 363 455 km (225 840 mi).

Moon before descending node

9 days after ascending node on 12 September 2027 at 11:26 in ♒ Aquarius. The Moon is located north of the ecliptic over the following 4 days, until the lunar orbit crosses from North to South in descending node on 26 September 2027 at 06:04 in ♌ Leo.

Draconic month

9 days since the beginning of current draconic month in ♒ Aquarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon before northern standstill

13 days since the previous standstill on 8 September 2027 at 08:57 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.122°, the lunar orbit is extending northward over the next day to face maximum declination of ∠27.015° at the point of next northern standstill on 22 September 2027 at 20:33 in ♊ Gemini.

Syzygy in 8 days

In 8 days on 30 September 2027 at 02:36 in ♎ Libra the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
